1. ### Perpendicular Acceleration

when a perpendicular force acting how it can take circular path.
2. ### Super conductors exhibit infinite current?

super conductors exhibit infinite current?why
3. ### Can a dielectic MATERIAL IS A INSULATOR?

When a dielectric material insert between two plate capacitors the conductivity may increase. Normally we talk that a dielectric is insulator?but how can it increases conductivity?
4. ### Newton's 2nd Law

generally earth has some velocity.when it loss its path there is a chance to fll of world with out accelration.
5. ### Copper wire resistance problem

i mean 9its diameter
6. ### Copper wire resistance problem

it resistance will be increased by two times.
7. ### Milk In The Coffee

i think, when u add milk first then it follows zeroth law of thermodynamis. then after some time it follows the law.but after waiting of 5 minutes there will be no distribution of heat.
8. ### Copper wire resistance problem

its resistance will be increased.because R is always inversely proportional to length
9. ### Question on young's double experiment

why we have to kept opaqe screen parllel to the two slits in young's double slit experiment?
10. ### Calculating equatorial velocity

hi,friend in your equation how we have take a=g.that is for surface on earth and although 'g' is not constant at all.
11. ### Calculating equatorial velocity

earth has both rectilinear and rotatory motion.but you take a=v^2/r.so your assumption is wrong.
